Definitions

  • the invention relates to a method according to the preamble of the main claim. Specifically, the Invention on a method for joining workpieces Titanium aluminide using a soldering process.
  • TiAl titanium aluminides
  • a joining process for such workpieces shows, for example U.S. Patent 5,318,214. This is where the joining takes place TiAl workpieces using a solder which is placed in an oven is heated together with the workpieces.
  • the oven e.g. vacuum oven or protective gas oven
  • Effort can be made because of the work pieces positioned accordingly to each other and pressed against each other Need to become.
  • Such a process is commercial therefore not applicable.
  • Another disadvantage arises the thermal influence on the workpieces, which leads to undesired Structural changes can lead. Also comes undesirable faults, especially when joining of thin-walled sheets.
  • U.S. Patent 5,785,775 shows an electrical welding process for workpieces made of titanium aluminides. This can, however Cracks in the weld seam, which are caused by further elaborate processing steps must be eliminated (see US 5,873,703 A).
  • the invention has for its object a method of to create the type mentioned above, which at simple and inexpensive implementation while avoiding the disadvantages state of the art high quality results supplies.
  • the method according to the invention is characterized by a number significant benefits.
  • the method according to the invention is in particular for joining of TiAl sheets particularly well suited. It proves It is particularly advantageous that the sheets or workpieces can also be bluntly joined. So it can be done to avoid overlapping joints or the like, the with such materials of the workpieces the high geometrical accuracy requirements only very much are complex and expensive to produce. In the state of the art can only overlap such as superplastic forming or hot forming become.
  • the inventive method allows both To do without protective gas ovens or vacuum ovens.
  • the brackets or clamping devices for the workpieces can be very simple, because the joining at room temperature and can be done under atmospheric pressure.
  • the workpieces can also be used with a Soldering gap be joined so that tight fits are dispensed with can be. Edge misalignment and column are due to the melting Solder bridged safely and easily. So is a simple butt-butt design for preparation for joining sufficient when using the method according to the invention.
  • gaps may even be desirable, because the better plastic deformation behavior of the solder compared the shrinkage stresses occurring in the base material Cooling of the solder from the solder and thus the brittle base material protected against micro and macro cracks is. This replaces that described in the prior art, quite complex preheating and cooling regimes in laser welding from TiAl.
  • the inventive method leads to a very inexpensive Manufacture of structures from TiAl workpieces. Since these are not cold-formable, it is according to the invention possible, even complex structural components, in particular from Sheet metal, easy and inexpensive to join.
  • the solder using the method according to the invention only directly in the area of the one heated by the laser beam Position melts, can be complex, high temperature resistant or scale-resistant special mounting devices to be dispensed with. Furthermore, it is not necessary on the joining areas during the joining process To exert pressure. Overall, the procedure can be performed at room temperature and atmospheric pressure, where a protective gas atmosphere only locally in the area of influence of the solder by the laser must be present.
  • a ductile material is used in a particularly favorable manner Solder or a ductile solder material is used. This can possibly arise thermal stresses or expansion stresses collect or dismantle so that the workpieces are not affected become.
  • Fig. 1 shows two workpieces 1, 2, which by means of a Lots 3 are to be connected.
  • the Arrows F schematically use the required force a biasing device, not shown, in order to melt the solder 3 in an oven atmosphere to fit both workpieces 1 and 2 exactly.
  • Fig. 2 shows an embodiment in which the Workpieces 1, 2 are butt-connected by means of the solder 3.
  • a laser 4 is shown in a schematic manner. additionally is the introduction in the area of heating by the laser 4 represented by protective gas 5.
  • protective gas 5 As can be seen from the illustration results in an edge region 7 of the workpieces 1, 2 practically no heat input.
  • a ductile solder 3 this can occur when it occurs Deform tensions in the solder during the joining process, see above as shown by the convex surface areas is.
  • the melted Lot with the help of a bath fuse 8 in the form of a Rail on the underside of the seam secured against sagging.
